Kanye West wishes Kim Kardashian could be pregnant all year long...why?

Kanye West wishes his wife Kim Kardashian West could be pregnant all year long, according to US reports.

The 38-year-old rapper is reportedly obsessed with his wife's growing curves and thinks she looks sexier than ever.

A source close to the couple, who are expecting a baby boy in December and already have two-year-old daughter North, told gossip website HollywoodLife.com: "Kanye wishes Kim could be pregnant all year long.

"They have the most adventurous and crazy sex when she's pregnant.

"The New Slaves rapper previously admitted he thinks the brunette beauty is "the most beautiful woman of all time."

While earlier this year, the Keeping Up with the Kardashians star, 34, confessed she and the rapper were having "sex 500 times a day" in a desperate bid to conceive another baby.

She added: "It's, like, so frustrating. I'm exhausted and I think I'm just making this all about the wrong things. Like, I'm forcing it, so we just need relax.

"We just need to not stress it, not plan so much, and just go with the flow."
